Monitoring in patients with preserved left ventricular function After Diagnosed acute Myocardial Infarction
- Rationale – despite modern optimal therapy, a large proportion of patients remain at high risk for MACE following MI
- Implantable cardiac monitors (ICM) have shown up to 80% of patients experience an arrhythmia prior to MACE in MI with reduced EF ≤ 40% – CARISMA trial (n=297, mean 2yr f/u)
- Objective: whether early diagnosis of cardiac arrhythmias, with ICM and remote monitoring, and its consequent treatment, reduce MACE
- Prospective, randomised (1:1), parallel-group, open trial;
Primary composite endpoint:
- Time to first MACE – cardiovascular death, first acute unscheduled hospitalisation or urgent visit for worsening of patient status due to heart failure
- First acute unscheduled visit for:
- Arrhythmia
- ACS
- Stroke
- Major bleeding
- Systemic embolism
Secondary endpoints:
- primary composite points separately, WHO-5 well-being index
